Reliable Protection for High-Current Low-Voltage Circuits
DIN-type gG fuse links provide full-range protection against overload and short-circuit currents. When excessive current passes through a protected circuit, the fuse element operates to interrupt the fault current, helping protect cables, conductors and connected electrical equipment against potentially damaging electrical conditions.
The ABB OFAF2H500 combines a 500 A current rating with a standardised DIN size 2 format, making it suitable for industrial switchboards, distribution panels and other high-current low-voltage installations. Its gG characteristic provides versatile protection across a wide range of general electrical distribution applications.
Typical Applications
- High-current low-voltage electrical distribution systems.
- Industrial switchboards and distribution panels.
- Cable and conductor overcurrent protection.
- Industrial machinery and electrical equipment.
- Fuse switches and fuse bases using compatible DIN size 2 fuse links.
- Commercial and industrial power distribution installations.
